혹시 해결 방안을 알려주실 수 있을까요..?
Single로 진행했고,
Main 장비는 PowerEdge R750에 Ubuntu 22.04.5 설치해서 진행했고,
서브들은 VMWare ESXi로 IP 3개를 파서 Ubuntu 22.04.5 를 설치해서 Worker Node로 진행하려고 했습니다.
서브 없이 메인만으로 하는 방법이 있으면 그것도 같이 알려주시면 좋겠습니다.
방법은 유튜브를 보면서 설치 과정을 따라하던 도중에 에러가 발생했고, IP는 그냥 마음대로 적은 IP여서 신경 안쓰셔도 될 것 같습니다.
Master IP : 10.10.10.81
Worker IP : 10.10.10.34 ~ 10.10.10.36 으로 구상하여 진행했습니다.
